The terms, conditions, and details of our warranty vary from product to product. Specific warranty details can be found below.

Tamerx Diesel Products provides a replacement warranty on all of our parts. The duration and mileage limitations of the warranty vary by product and are specified on the product's detail page/item listing.

Please note that the warranty covers replacement of the part and the cost of shipping the replacement part to you only. It does not cover any shop, labor, towing, or any similar or related costs. This is not a "money back guarantee".

If you experience a problem with your part or it is not functioning properly, the correct warranty procedure is to call us at (510) 257-1777 (8:00 AM - 5:00 PM ET Monday through Friday). Be sure to have your order number and/or other relevant order information ready so we can easily locate your order and resolve your issue as quickly as possible. From that point, we will review with you any troubleshooting steps that may need to be taken and other areas or systems that can be checked to rule out external problems contributing to your part's issue. If a replacement is determined to be necessary, we will then arrange for your replacement part to ship out ASAP and issue any necessary return shipping labels and/or documents.

As is the case for the majority of the diesel products sold on Tamerx Diesel Products, your part's warranty is active as soon as you install it. In some other cases, warranty activation is contingent upon you sending us your core (i.e., your old part). Tamerx Diesel Products will provide you a return shipping label for parts that have a warranty with a core return condition. When we have received your core return, the part's warranty coverage begins. We reserve the right to void the product warranty if your core is not received within the allotted time, or if it isn't received at all. If the warranty for the diesel part you are purchasing has a core return requirement, it will be clearly noted on the product detail page/item listing.

What is a Core Charge?

A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.

30 Day Core Charge Hold

You authorize Tamerx Diesel Products, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.

The customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Tamerx Diesel Products offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.

The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.

All fluids must be drained.

If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.

Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Tamerx Diesel Products core charge presented to you online today with your item is representative of the most common core charge.

Emission systems on modern diesel trucks are engineered to reduce harmful pollutants and help vehicles meet stringent environmental standards. The Cummins L9 SCR 2022–2024: OEM 5507875 is a Selective Catalytic Reduction (SCR) component that plays a crucial part in lowering nitrogen oxides (NOx) produced during combustion. For truck owners and maintenance teams, understanding how this SCR unit functions and why choosing the correct OEM part matters can help maintain cleaner operation and system reliability.

  • Designed specifically for Cummins L9 engines from 2022 to 2024, the OEM 5507875 SCR unit fits directly into the emission aftertreatment system for accurate integration.

  • The SCR (Selective Catalytic Reduction) system reduces NOx by injecting diesel exhaust fluid (DEF) into the exhaust stream, where a catalytic reaction converts the pollutants into nitrogen and water vapor.

  • Choosing the genuine OEM 5507875 SCR ensures proper compatibility with your engine’s emission control strategy, helping prevent diagnostic trouble codes and false service warnings.

  • A properly functioning SCR supports precise DEF dosing, which promotes effective NOx reduction while minimizing unnecessary DEF consumption.

  • Replacing worn or compromised SCR components with the correct OEM part helps reduce the likelihood of emission faults that can trigger warning lights or impact operation.

  • Reliable SCR performance enhances communication between emission sensors and the engine control module, leading to fewer false alarms and smoother system response.

  • Built to meet Cummins’ original manufacturing standards, this SCR module offers durability to handle heat, vibration, and the operating conditions typical of highway and regional driving.

  • Installation is practical for professional technicians and maintenance crews during scheduled emission system servicing or part replacement intervals.

Selecting the Cummins L9 SCR 2022–2024: OEM 5507875 from Tamerx Diesel Parts means equipping your truck’s emission control system with a quality component engineered for your engine’s specific needs. With a dependable SCR unit in place and proper maintenance, your truck will remain emission-compliant, dependable, and ready for everyday operation.

The Selective Catalytic Reduction (SCR) system is built to withstand high exhaust temperatures and continuous operation. Its internal catalyst is designed to convert nitrogen oxide (NOx) into less harmful emissions using Diesel Exhaust Fluid (DEF). However, certain conditions can cause internal damage that reduces efficiency or leads to complete failure. Understanding what harms the SCR internally can help prevent premature replacement.

  • Oil contamination is one of the leading causes of internal damage. Excessive oil consumption or turbo-related issues can allow oil to enter the exhaust system, coating and degrading the catalyst material.

  • Coolant leaks within the engine can introduce harmful deposits into the exhaust stream. When coolant passes through the SCR, it can leave behind residue that permanently damages the catalyst.

  • Poor-quality or contaminated DEF may introduce impurities that interfere with the chemical reaction inside the SCR.

  • Excessive soot from unresolved Diesel Particulate Filter (DPF) issues can overload the system and restrict proper exhaust flow.

  • Overheating caused by improper regeneration cycles or exhaust restrictions can break down the catalyst substrate internally.

  • Physical impact or severe vibration may crack the internal substrate, reducing efficiency and triggering fault codes.

Internal SCR damage often results in reduced emissions efficiency, warning lights, and possible engine derate. Promptly addressing engine leaks, maintaining proper DEF quality, and keeping the entire aftertreatment system in good condition can help extend the life of the SCR and prevent costly repairs.

Start by checking DEF quality, fill level, and related sensor connections before inspecting the SCR module itself. These factors often contribute to symptoms that appear to originate from the SCR.

There’s no set replacement schedule, but the unit should be inspected if emissions issues arise or sensors report performance degradation. Worn or damaged SCR units should be replaced promptly to maintain compliance.

Yes, very low temperatures can temporarily impact DEF flow and SCR reaction efficiency until normal operating temperature is reached. Many systems include DEF heaters to minimize cold-weather effects.

Efficient NOx reduction helps reduce stress on exhaust components and prevents frequent derates due to emissions faults. This stable emissions control supports smoother long-term engine operation.
